Abstract
Glass fiber is first pre-treated with water solution of coupling agent and then mixed homogeneously with caprolactam monomer. The mixture is heated, dewatered, added with catalyst and activating agent, cast fast in preheated mold to produce the cast composite nylon material with high-content reinforcing glass fiber of the presnt invention after demolding. The composite material thus prepared has relatively higher tension strength, tensile elastic modulus, bending strength and bending elastic modulus.
Description
The present invention relates to a kind of preparation method, belong to materials science field with cast composite nylon material with high-content reinforcing glass fiber.
Monomer cast nylon is under normal pressure fused raw material caprolactam monomer to be made catalyzer with alkaline material, with auxiliary agents such as activators, directly inject the mould that is preheating to certain temperature, material carries out polyreaction soon in mould, condenses into the tough and tensile solid blank of white.The characteristics of monomer cast nylon are: light weight, density are generally 1.15～1.16; Vibration and noise reducing; Good rebound resilience; Have wear resistance and self lubricity, be suitable under the operating mode that can not add lubricant, using; The favorable mechanical performance, physical strength is more much higher than common nylon, good toughness, shock resistance, antifatigue.Monomer cast nylon obtains to use at a lot of industrial circles as the wear-resistant self-lubricating engineering plastics, as large-scale ball valve seal ring and the axle sleeve on oil, the natural gas transmission pipeline, the piston body of rig pump, various drive mechanism parts such as bearing shell, axle sleeve, ship propeller, weaving loom shuttle, gear etc.Along with the expansion of monomer cast nylon practical application, to its demands for higher performance.Particularly its low physical strength of comparing with ferrous materials is difficult to satisfy the requirement of large-scale workpiece to material property.Therefore, when keeping its good characteristics, how further to improve its mechanical property, exploitation material potential becomes and enlarges its key in application.
The objective of the invention is to propose a kind of preparation method of cast composite nylon material with high-content reinforcing glass fiber, make this kind matrix material not only have the superperformance characteristics of monomer cast nylon, and have a tensile strength higher than monomer cast nylon, mechanical properties such as flexural strength, tribological property also is improved, thereby can go out the higher workpiece of supporting capacity with this material preparation.
The preparation method of the cast composite nylon material with high-content reinforcing glass fiber that the present invention proposes comprises following each step:

(2) glass fibre and the caprolactam monomer after will handling mixes, and the add-on of glass fibre is 20-40%, about fibre single thread diameter 10 μ m, length 100-200 μ m puts into the container internal heating to 110-130 ℃, makes material melting, container vacuumizes dehydration, and vacuum tightness is 10
-1～10
-3Pa;
(3) open valve, remove vacuum, add catalyzer sodium hydroxide, add-on: with monomeric mol ratio be 0.002～0.003: 1, be evacuated to 10
-1～10
-3Pa is heated to 130 ℃;
(4) open valve, remove vacuum, add the activator tolylene diisocyanate, add-on: with monomeric mol ratio be 0.002～0.003: 1;
(5) be cast to rapidly in the mould that has been preheated to 150-180 ℃, be incubated the demoulding after 5 minutes, be cast composite nylon material with high-content reinforcing glass fiber of the present invention.
Matrix material with method preparation of the present invention, the tool Main Feature is: tensile strength reaches 90Mpa-110MPa, modulus in tension reaches 4100Mpa-7500Mpa, flexural strength reaches 160Mpa-210Mpa, bending elastic modulus reaches 3800Mpa-6900MPa, notch shock toughness reaches 11kJ/m-15kJ/m, all is greatly improved than the monomer monomer cast nylon; Tribological property has also had tangible improvement.
